./~/node-env-file/lib/index.js中的错误找不到模块：错误：无法解析模块'fs'

Question

因此，当尝试在我的config.js文件中要求使用node-env-file时，如下所示：

import Raven from 'raven-js';

const env = require('node-env-file');
env('.env');

我收到以下错误消息：

./~/node-env-file/lib/index.js中的错误找不到模块：错误：无法解析C：\\ Users \\ d0475 \\ Documents \\ Projects \\ learn-redux-graphql \\ node_modules \\ node中的模块'fs' -env-file \\ lib @ ./~/node-env-file/lib/index.js 3：9-22

我的webpack配置文件如下：

var path = require('path');
var webpack = require('webpack');

module.exports = {
  devtool: 'source-map',
  entry: [
    'webpack-hot-middleware/client',
    './client/app'
  ],
  output: {
    path: path.join(__dirname, 'public'),
    filename: 'bundle.js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin()
  ],
  module: {
    loaders: [
    // js
    {
      test: /\.js$/,
      loaders: ['babel'],
      include: path.join(__dirname, 'client')
    },
    // CSS
    { 
      test: /\.styl$/, 
      include: path.join(__dirname, 'client'),
      loader: 'style-loader!css-loader!stylus-loader'
    }
    ]
  }
};

这是什么，我该如何解决？

Answer 1

您需要告诉您的webpack配置您的节点环境 。 将node条目添加到您的webpack配置中，其中fs模块的值为空：

var path = require('path');
var webpack = require('webpack');

module.exports = {

    /* Your exisitng config as above */

    node: {
        fs: 'empty'
    }
};

Answer 2

使用dotenv-webpack解决了该问题。
